Understanding the characteristics of urban plant multidimensional diversity and green spaces (UGSs) landscape patterns is central theme ecology, providing theoretical support for UGSs management biodiversity conservation. Taking Changchun, a provincial city, as an example, total 240 plots were surveyed using stratified random sampling method. We studied effects park construction period on diversities, spaces, their associations in Changchun City, Northeast China. The results indicated that woody species tree attributes both highest 2001–2020 lowest before 1940. However, shrub completely opposite. Diameter at breast height (DBH) index (Hd) was 1940 2001–2020. (Hh) showed opposite trend. Phylogenetic structures divergent parks constructed 1940–2000 period, while could not be determined. In contrast, phylogenetic structure clustered across all periods. Landscape pattern metrics varied significantly among different Total Area (TA) structural equation model (SEM) revealed periods exerted significant direct diversities spaces. Specifically, indirectly affected through influenced species’ diversity. What more, Patch Density (PD), Edge (ED), Aggregation Index (AI) correlated with Hh, which had effect Shannon–Wiener (H′t). Overall, can enhanced regulating patterns, rationally selecting species, optimizing configuration. These above provide scientific references configuration communities selection parks, offer important guidance conservation enhancement.

Nature-Based Solutions in Urban Green Infrastructure: A Systematic Review of Success Factors and Implementation Challenges

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 818 - 818

Published: April 9, 2025

Nature-Based Solutions (NBSs) have gained prominence in urban planning as integrative strategies that utilize natural processes to address complex environmental and societal challenges while advancing green infrastructure development. Despite growing academic interest, the practical integration of NBSs into remains hindered by fragmented methodologies limited understanding context-specific implementation dynamics. This study contributes addressing these gaps through a systematic review bibliometric analysis 90 peer-reviewed articles published between 2014 2024. It examines range employed infrastructure, factors shaping their successful implementation, barriers, financial, technical, social, political, constrain adoption. The also explores roles key stakeholders, including local governments, private actors, communities, planning, execution, maintenance NBS projects. findings reveal both conceptual convergence contextual variation how are deployed evaluated, highlighting critical enablers, such spatial justice, governance integration, financial viability, technical capacity. By clarifying conditions under which function effectively, this offers insights for researchers policymakers seeking embed approaches within sustainable development frameworks.

Spatiotemporal Changes in Ecological Network Structure and Enhancing Territorial Space Management in Guilin, China

Sustainability, Journal Year: 2024, Volume and Issue: 16(24), P. 11018 - 11018

Accelerated urbanization and the excessive exploitation of tourism industry are leading to a diminution ecological spaces in tourist cities. Ecological networks an effective method for improving patch connectivity maximizing space. However, previous research on predominantly focuses static snapshots, ignoring fact that landscape entities with considerable spatiotemporal structural dynamics changes. To fill this gap, we first constructed Guilin 1990, 2000, 2010, 2020, employing integrated valuation ecosystem services tradeoffs (InVEST) model, morphological spatial pattern analysis (MSPA) method, circuit theory. Subsequently, analyzed evolution proposed strategies territorial space management. The results showed sources corridors were generally decreasing both number areas (length), coupled notable increase pinch points barriers over 30-year period. corridors, points, associated sources. Structural evaluation revealed during 1990~2020, value α (network closure) exceeded 0.7, β (line point rate) surpassed 2, γ connectivity) was greater than 0.8, indicating robust overall within networks. observed decline these three indicators time suggested reduction available dispersal pathways species networks, highlighting need protective measures optimization strategies. Consequently, network conservation development patterns enhance management Guilin. This study addresses critical knowledge gap offers valuable insights mitigating habitat fragmentation enhancing
